Figs. 2 to 5 show an embodiment ofthe ignition device 40 in a unitarystructure.

Housing tube rests on a base71 support-y ing coil 4i and core 42. -Core42 includes a bundle ot` iron wires 72 and a center rod 7 3 engaging anut 74 at its upper end and a nut 75 at its lower-end. Nut 74 bearsIagainst Washer 76 in turn bearing against wires 72 and a non-conductingsleeve k7 7 in turn bearingagainst an'end bell 4l ot coil 4l. Bytightening nuts 74 and 75 the core and coil assembly issecured upon thebase 7l. The yoke 53 is attached to end hell Lil and theI holding coilcore projects through a hole 78 in non-magnetic vibrator base 79, thishole being lined with a non-conducting Washer 78a as shown-in Fig. 2.Thus core 54 is insulated electrically Jfrom the rest of the structure.vThe hole 8.0 in base 79 is to permit the upper-end ot core a2 to extendythrough it.v The base 79 supports the fulj crum post 49 which isattached thereto by tubular rivets Si and82 which are insulated from thebase 79. `A bracket 83 riveted to base 79 supports the adjusting screw65. The base 79 is provided With a recess in Which condenser G2 rests`this condenser being grounded on base 79 and secured thereto As shown inFig. 4, the housing tube 70 supports the terminals 59. ,57 anddesignated by CB (mcaning-circuit breaker),

G (meaning ground) and B (meaning batt-erf), respectively., Terminal Gris at` vtached to a metal clip which makes contact with the base 79 whensecuredv to tube70. v The base 79 supports a vibrator cover 91 Yattached thereto by 'anut 92 engaging ay post 93 extending through saidvcover 91 and at-v tached to the base 79.

YWhile the torni ot mechanism herein shown and described constitutes Aapreferred form of embodiment ot the invention, it is to be understoodthat other forms might be adopted, all coming Within the scope of theclaims which follow.

What l claim is as follows: l. In an ignition system, thecombinationwith engine ignition' apparatus including a current source,ignit'ion'coil, an'y engine operated timer and an 'enginespark plug; ofa vibrator ignition coil; an auxiliary spark plug connected to' saidvibrator coil and means associated with said vibrator coil andcontrolled by said engine timer torpermitting` the vibrator coil to vbeoperative only when the timer contacts are closed.

2. In an ignition system,-.the combination with engine Vignitionapparatus including a current source, ignition coil, anengine operatedtimer and. an engine spark plug; ot a vibrator ignition coil including acore andvibrating armature; an auxiliary spark plug connected to saidvibrator coil; and an auxiliary electromagnet associated with v saidarmature and connected i n-shunt with saidtiiner contacts for preventingoperation ot said armature when said timer contacts are opened. Y y

Inan ignition system, the combination with engine ignition apparatusincluding a current source, ignition coil.`an engine operated timer andan engine spark pliw; of a vibrator coil including a core and vibratingarmature; an,` auxiliary spark plug connected to said vibrator coil; andan auxiliary magnet having a core in magnetic circuit with said vibratorvcoil core and .armature and a Winding` in shunt with the timercontacts. i f f v- 4. ln a device of the character described,

'the' combination Wit-h a housing having a removable closing memberprovided with openingss; an ignition coil having a core located Withinsaid housing. and a control y ling coil having a core located Withinsaid housing, both ot said cores proyecting through openings in saidclosing member; a

ing member in proximity to said cores; a

lvibrating armature supported by said closcontact supported by saidarmature; and a contact supported by closing member.
